Hi,
Pleas ask me,what are the main disadvantages of lagrange multipliers method in meshless methods?

Use Vumat to simulate the hot ductile fracture criterion of Freudenthal
Dear everybody，
I have just studied Abaqus and would like to use Vumat to simulate the hot ductile
fracture criterion of Freudenthal which have the equation: D=integral(0-fracture strain)
of (Smises stress)*d(strain). The fracture will be appear when I reach 1 unit.
Could you please show me how to write algorithm adding temperature to calculate (D) and
out put (D) in Vumat.
thanks you so much
I am looking forward to hearing from you

Paper on the mechanics of motility of a family of unicellular organisms called euglenids
Dear colleagues,
I wanted to draw your attention to a paper published last year in PNAS
http://www.pnas.org/content/109/44/17874
where we analyze physical aspects of how euglenoids move

A question on linear materials in large strain analyses
Hi there,
I came across the following question on another website, which I found intriguing:
PhD Studentship@University of Southampton, UK - Wet Adhesive Poro-Viscoelastic Contact Along Human Skin Surface
Skin, the largest organ of the human body, acts as a
multi-functional biophysical interface to the external environment. The serial
interfacial phenomena along the skin/environment conjunction, particularly when
interacting with cosmetic and consumer goods (e.g. razor and shave preparation)
is determined by the interplay between the chemical structure and arrangement
of stratum corneum lipids,
environmental factors (e.g. hydration level) and also the physical
characteristics of skin surface relief. Therefore, the chemical and biophysical
properties of the stratum corneum
need to be considered jointly to approach the complexity of skin tribo-physics.
These technical challenges present outstanding opportunities for high quality
PhD Studentship@University of Southampton,UK-The Design of Lubricant-Surface Interaction for Reduced Boundary Friction and Wear
Mechanical losses account for 15% of total energy loss in an
IC engine where 45% of these losses result from friction of piston-ring
assembly. An increase in mechanical efficiency of 10% could lead to improved
fuel consumption of 1.5%. Taking into account the large number of vehicles on
road (30 million in the UK in 2010 according to the Society of Motor
Manufacturers and Traders) and fuel
consumption of 12.5 miles/litre, the potential fuel saving would accrue to
approximated £647 million/annum, which is substantial to the country's economy.
